ATTACHMENT FOR PAINTERS STAGES.

Speccaton of Letters Patent.

Patented Feb. 13, 1912.

Application led December 14, 1910. Serial No. 597,289.

T o all 'whom it may concern:

Be it known that I7 CHARLES E. SHARP, a citizen of Finland, intending to apply for citizenship in the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Attachments for Painters Stages, of which the following is a specification.

This invention relates to painters appliances and particularly to attachments for painters stages, whereby the stage may be spaced from the wall upon which the painter is operating.

A further object is to provide a means whereby a stage having the attachment forming the subject-matter of the present invention may be moved vertically and horizontally without in any way damaging the wall.

This invention also contemplates the provision of adjusting means whereby the distance of the stage from the wall may be regulated to suit the operator.

With the above and other objects in view, this invention consists of the construction, combination and arrangement of parts all as hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which- Figure 1 is a top plan view illustrating the present invention attached to a stage or ladder; Fig. 2 is a front elevation thereof; Fig. 3 is a top plan view partly in section showing the parts adjusted to an inoperative position; Fig. 4 is an elevation of the adjusting plate; Fig. 5 is a transverse section taken on the line 5-5 of Fig. 2; Fig. 6 is a section taken along line 6-6 of Fig. 2; Fig. 7 is a transverse section taken along line 7-7 of Fig. 2; Fig. 8 is an elevation illustrating the attachment of the present invention in its eXtreme adjustment.

The attachment forming the subject-matter of the present invention comprises a plate carrying pivotally connected sections which have at their outer terminals means for securing said plate to the stage or ladder. One of the pivotally connected sections has slidably mounted thereon a plate which carries at its outer terminal a ball or rotatable bearing surface which contacts with the wall, thereby spacing the stage or ladder from said wall. Means are provided whereby the angle at which the pivotally connected sections operate with respect to the carrying plate may be regulated, thus supplying a double adjustment with respect to the distance of the stage from the wall.

Referring more particularly to the drawings, A indicates a stage or ladder. A carrying plate 10 which has its terminals beveled is detachably carried by one side of the stage or ladder A as hereinafter more fully described. Adjacent to one terminal of the plate 10, and disposed on each side thereof are the plates 11, said plates having the vertical ears 12 formed thereon. A wooden bar 13 is pivoted thereto through the instrumentality of the metal strips 14 disposed on each side of said bar. The strips 14 are connected at their upper terminals by the plates 15 disposed on the top and bottom of the bar 13, said plates and bar being concaved to form a housing for the bearing ball 24 which is mounted thereon.

The bar or section 13 is split adjacent to the plates 15 and is provided with the guideways 16 on each side thereof, said guideways extending from said split portion to the lower terminal of the bar. A plate 17 is slidably mounted in the split portion of the bar 13 and is provided with the arms 18 which move in the guides 16. Lateral or vertical flanges 19 are disposed on each edge of the plate 17 and arms 18, said plate being movable to the outer extremity of the bar 13 and located between the strips 14 and said bar. A strap 20 is secured to the flanges 19 of the arms 18 and is provided with the U- shaped hook members 21 which engage the strips 14 on each side of the bar. This strap carries a set screw 22 which operates against the under side of the bar 13, thus retaining the plates 17 in various positions and regulating the distance the same is projected from the bar 13. A circular band 23 is pivotally mounted in the semicircular recess of the plate 17 and has journaled therein the rubber or wooden ball 24. The pivot of this ball is so arranged that the rotation of the ball is vertical. Thus upon the vertical movement of the stage, the ball operates against the wall and causes the movement of the stage to be greatly eased, and prevents the wall from being damaged thereby.

A pair of longitudinally extending strips of metal 25 are pivoted to the projecting ends of the strips 14 carried by the bar 13, said strips being of spring material and having a bearing and bracing member interposed therebetween.

A brace 26 is interposed between the arms or strips 25, and has a curved end 27 to permit the movement of the ball 24. A bearing plate 23 is rigidly secured to the lower terminals of the arms formed by the brace 2G and is adapted to rest on the plate 10. A U-shaped pin 29 pierces the strips 25 and is provided with the arms 29 and 29, the arm 29 being encircled by a spring 30 which tends to force the arms by the strips 25 outwardly. A block 31 is interposed between and secured to the arms 29 and 29 of the U-shaped pin 29 and has a set screw 32 therein operating therethrough which bears upon the plate 23. Angular clamp members 33 are secured to opposite ends of the pin 29 and engage the side of the stage A, being clamped in this position by the thumb nut 34. By turning the set screw 32 in one direction, the members 25 and 29 which carry the clamp members are forced outwardly from the side of the stage A and in this manner the said members 33 may be readily caused to firmly engage the stage, the set screw 32 causing separating movement of the parts 31 and 2S.

A bearing 35 is mounted, on the bar 13 and has secured thereto the resilient arms 36, said resilient arms having the angular slots 37 in the terminals thereof, said slots having a pin 3S slidably mounted therein. A spring 39 is wound about said pin and tends to force the arms 36 apart while an angular clamp 40 is mounted on each extremity of the pin, said arms being retained in place by the thumb nut 41. A block 42 is mounted on the pin 38 and is pierced by a set screw 43 which bears against the plate 10.

In the actual use of the invention one or more of the devices is attached to the side of the stage near the wall to be operated upon and clamped upon said side by means of the thumb nuts 34 and 41. The desired distance from the wall is secured by loosening the nut 34 and moving the pivoted arms 25 and 14 outwardly causing the ball 24 to bear against the wall as will readily be. seen. Should the limit adjustment of the arms 25 and 14 be not sufficient to give the desired space from the wall, the bar 13 carrying` the ball 24 may then be moved outwardly and clamped in position by the set screw 22 to provide further spacing, as most clearly shown in Fig. 8 of the drawings.

From the foregoing it will be understood that the parts 14 and 25 practically constitute a frame composed of sections pivotally connected together at one end and having pivotal connections at the other ends indirectly to the stage A. Further, the member 17 is practically a slide movable on one of said sections in alinement with the latter, and the arms 36 constituting a brace performing a function somewhat similar to that of the brace 26.

Having thus described the invention, what is claimed as new is:

1. In combination, a painters stage, and a wall engaging attachment therefor comprising a frame composed of sections pivotally connected at one end to the stage and pivotally connected together at their other ends, means for holding said sections at various angular adjustments, a slide adjustably mounted upon one of said sections, and a bearing member carried by said slide to engage with a wall or the like. y

2. ln combination, a painters stage, and

a wall engaging attachment therefor comprising a frame composed of sections pivotally connected at one end to the stage and pivotally connected together at their other ends, means for holding said sections at various angular adjustments, a slide movably mounted on one of said sections, means for holding said slide at various adjustments projecting from but in alinement with the section carrying the same, and a bearing member to engage a wall carried by the outermost portion of said slide.

3. ln combination, a painters stage, and means for spacing said stage from a wall consisting of a frame composed of sections pivotally connected together at one end and adjustably connected at the opposite ends to the stage, a wall engaging member, and piv otal supporting means for said wall en gaging member arranged in alinement with the vpivotal connection between adjacent ends of said sections.
